How to put single space in field_input?

[Frank The Tank]

Using a field_input with leading or trailing spaces around text seems to work fine, but how do I allow someone to define a field_input with *only* a space character?  When I inspect the serialized XML it appears to remove spaces from the XML workspace.

Unable to recreate.  Seems to work properly:

There's one space in that input, and there is a space in the XML (as seen in the XML tab).

Thanks, you are right.  Apparently this is happening when passing the blockly XML to another parser after serializing.  It looks like XML is a bit loose on whether whitespace should be preserved unless xml:space="preserve" attribute is present?
